Abstract

The efforts to achieve optimal results in the development of oil palm cultivation one of which is the use of the planting medium. Palm oil seedlings require planting medium that has the chemical and physical properties are good. Media palm nurseries generally consist of topsoil are mixed with sand and organic matter which is expected to obtain a good medium fertility premises. Top soil needs more difficult, so we need to look for alternative media to growing media prenursery palm oil. This study used randomized complete design and experiment arranged in seven media with four replications. The applications method of media: 100 % topsoil (A), topsoil and salvinia compost (1:1) (B), topsoil and coir palm oil (1:1) (C), topsoil and salvinia compost (1:2) (D) , topsoil and coir palm oil (1:2) (E), coir palm oil and salvinia compost (1:2) (F) , topsoil , salvinia compost, and coir palm oil (1:1:1) (G). All data were analyzed for variance. Data analysis followed by separation of means using LSD test with significance level of 5%. The resulted showed that both time and applications method of topsoil have affect on growth component. The best application method was topsoil, salvinia compost, and coir palm oil increased dry weight and root dry weight. Keywords: Prenursey, topsoil , salvinia compost, coir palm oil

Abstract

The effort to increase productivity of coffee plants in long dry season upland of Ultisol include application of Vesicular Arbuscular Mycorrhizae (VAM) on coffee plants, because its application only one time and its affect along a life time of coffee plant in the field. This study aims to determine the exact time and applications method of VAM on growth coffee seedlings. This study used 10 g VAM/polybag or 800 spores as basic treatment. This study used randomized block design and experiment arranged in factorial 3 x 5 with three replications. The first factor was the time of VAM application: given at nursery seedlings (W1), given at transplanting (W2), and combine of given at nursery seedlings and transplanting (W3). The second factor was the applications method of VAM: without VAM inoculant (C0), VAM inoculant placed around the coffee seedling root up to a depth of 2 cm below root (C1), up to a depth of 4cm below root (C2), up to a depth of 6 cm below root (C3), and VAM inoculant mixed with media planting (C4). All data were analyzed for variance. Data analysis followed by separation of means using LSD test with significance level of 5%. The resulted showed that both time and applications method of VAM have affect on growth component and root infection rate. The best application time was double application, i.e. combine of given at nursery seedlings and transplanting, and the best applications method was VAM inoculant placed around the coffee seedling root up to a depth of 2 cm below root, both of them increased plant height, stem diameter, leaf amount, long of root, and root infection rate.

Abstract

Kiambang (Salvinia natans) which a water plant became a seriously problem in the use of Reservoir Batutegi, because nearly 80% of its surface covered by Salvinia natans. The presence of highly abundant of Salvinia natans have highly potential to be used as a source of organic fertilizer. The purpose of this study was to examine the effect of the application of biological technology (decomposers) and cow manure on the quality of the resulting compost kiambang. This study used randomized block design and experiment arranged in factorial 4 x 4 with three replications. The first factor was the dose of decomposers which consists of 4 levels, namely A1 = 0 ml, A2 = 20 ml, 30 ml dose = A3, and A4 = 40 ml decomposers per quintal kiambang respectively. The second factor was the dose of cattle dung, i.e. B1 = 0 kg, B2 = 10 kg, 20kg = B3, and B4 = 30 kg manure per quintal kiambang. The results showed the compost that has the best quality in terms of physical and chemical compost was the compost derived from the treatment of 30 ml and 40 ml decomposers per quintal kiambang which combined with 10 kg, 20 kg or 30 kg manure per quintal kiambang. Keywords: Salvinia natans, decomposers, cow manure, compost quality
